Pretty much what the title says. I have an Asus P5Q Pro and installed a few apps from the CD that came with it. Here are some examples why you shouldn't do it: EPU-6 Engine: It doesn't work under "overclocking mode" which is basically that if you have put "AI Tuning" in BIOS to Manual. If you enable it, it shows "how much you've saved CO2 so far"... That's pretty **** propaganda IMO. If you use it, it'll crash your computer. The power saving settings aren't stable at all. I got two bluescreens, the second came when I restarted right after the first one. It basically just doesn't work. It can only control some newest Asus graphics cards. AI Nap Doesn't save nearly any power. There's a bug in it, which causes the VCore to drop back to stock when leaving AI Nap mode. That causes fatal instability on OC'd systems. SmartDoctor This is needed for the GPU control in EPU-6 to work. Only supports Asus graphics cards. Shows an unexplanative, stupid error message ("Can not find graphics card information") on startup if a non-supported graphics card is used, or if you have a bad luck (the net is full of stories about this). Fan Xpert Does simply not work! The fan speeds don't change! AI Booster This one works, but nearly all changes need a system restart. No voltages except RAM voltage can be adjusted. There are bugs in it, such as the current tab closing after applying settings. On the top of this, there are spelling mistakes and bad translations in all of these programs!
